A few days ago, I blogged about visualizing CRAN dependency ranks which turned out to be a somewhat popular post. David Smith followed-up at the REvo blog suggesting to exclude packages already shipping with R (which is indicated by their 'Recommended' priority). Good idea! So here is an updated version, ...

A new version 0.2.7 of RInside is now available via CRAN. RInside provides a set of convenience classes which facilitate embedding of R inside of C++ applications and programs, using the classes and functions provided by the Rcpp R and C++ integrati... [Read more...]

An updated version 0.1.4 of the RcppExamples package is now on on CRAN. RcppExamples contains a few illustrations of how to use Rcpp. The NEWS entry is below: a new example was added illustrating use of the (vectorised) random-number generators... [Read more...]

A new bug-fix release of the RcppBDT package appeared on CRAN earlier today. David Reiner noticed that the functions getEndOfMonth and getEndOfBizWeek were not working right. These are convenience wrappers around the real functionality provided as a ... [Read more...]

The recent update by Søren Højsgaard's to his gRbase package for graphical models made it the 75th package to depend on our Rcpp package for R and C++ integration. So in a lighthearted weekend moment, I tweeted about gRbase being number... [Read more...]

Version 0.2.0 of the recently introduced RcppCNPy package for reading/writing NumPy data in R arrived on CRAN earlier today. The main change are the added ability to also write gzip-ed npy files, to suppress an automatic transposition as well as th... [Read more...]

Similar to yesterday's post about RcppGSL, we have another pure maintenance release to announce, this time of RcppClassic, the package supporting the deprecated older classic Rcpp API defined in the earlier 2005 to 2006 releases, is now on CRAN. Ther... [Read more...]

Conrad released version 3.2.4 of Armadillo yesterday. It contains a workaround for g++ 4.7.0 and 4.7.1 which have a regression triggered by the Armadillo codebase for small fixed-sized matrices. The corresponding RcppArmadillo package 0.3.2.4 arrived ... [Read more...]

A couple of days ago, I had posted a short Python script to convert numpy files into a simple binary format which R can read quickly. Nice, but still needing an extra file. Shortly thereafter, I found Carl Rogers cnpy library which makes reading and writing numpy files from C++ ... [Read more...]

A few days ago I had blogged about getting NumPy data in R by using a simple converter script. That works fine, but it is a little annoying to have to write an entire file only to read from it again. So I kept looking around for a better solution---and ... [Read more...]

A new release of the RcppBDT package appeared on CRAN earlier today. RcppBDT uses Rcpp, and in particular the nifty Rcpp modules feature of wrapping C++ code for R just by declaring the (class or function) interfaces. It uses this to bring in some useful functions from Boost Date.Time ... [Read more...]

Conrad releaser version 3.2.3 of Armadillo a few days ago, and the corresponding RcppArmadillo package 0.3.2.3 is now CRAN. (For these keeping score 3.2.1 never was a full release, and 3.2.2 containing fixes for a build issue that did not affect the ... [Read more...]

The other day, I found myself confronted with a large number of large files. Which were presented in (gzip-)compressed ascii format---which R reads directly via gzfile() connections---as well as (compressed) numpy files. The numpy can be read very ... [Read more...]

The bug-fix in version 0.9.12 of Rcpp turned out to be incomplete, so a new version 0.9.13 is now on CRAN and will get to Debian shortly. The Rcpp::Enviroment constructor is now properly fixed (using the global environment as a default value). As ... [Read more...]
